Type of vulnerability: This utility is intended to block IP
addresses showing suspicious behaviour, to disarm a potential
attack. In versions before 0.9.4, if configuration option
"allow_missing_dns" is set to no, it performs no blocking. This
setting is used in the example configuration file, which is
installed by default in Debian. Thus, systems using the suggested
or default configuration receive no protection.

This vulnerability provides no vector for an attacker, local or 
remote, to gain any privileges. It simply fails to provide the 
intended protection.

Mainline fix:
https://github.com/walterdejong/pam_shield/commit/afa7b246018787fe6028289c414c33292641e1e0


Debian bug report and fix:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=658830

Vulnerable versions: mainline up to and including 0.9.3. Debian up
to and including 0.9.2-3.2 First fixed versions: mainline 0.9.4.
Debian 0.9.2-3.3

Please use CVE-2012-2350 for this issue.
